Many studies report on the association between 2D:4D, a putative marker for prenatal testosterone exposure, and economic preferences. However, most of these studies have limited sample sizes and test multiple hypotheses (without preregistration). In this study we mainly replicate the common specifications found in the literature for the association between the 2D:4D ratio and risk taking, the willingness to compete, and dictator game giving separately. In a sample of 330 women we find no robust ...

A growing body of correlational studies suggests that sex hormones such as those contained in, or affected by, oral contraceptives (OCs) may impact economic behavior. However, despite widespread use of OCs among women in Western countries, little is known about their potential behavioral effects. The present study investigates whether OCs causally influence economic preferences. We randomly allocate 340 women aged 18–35 to three months of a widely used OC or placebo treatment. At the end of trea...

AbstractStromal factors have been identified as important for tumorigenesis and metastases of breast cancer. From 49 premenopausal women, samples were collected from benign or malignant tumors and the seemingly normal tissue adjacent to the tumor. The factors studied, with real-time polymerase chain reaction (PCR) and immunohistochemistry, were cyclooxygenase-1 and cyclooxygenase-2 (COX-1 and COX-2), syndecan-1 (S-1) and connective tissue growth factor (CTGF).COX-1 and S-1 mRNA levels were highe...

Objective To determine whether there is a causal effect of oral contraceptive (OC) treatment on general well-being and depressed mood in healthy women. Design Double-blind, randomized, and placebo-controlled trial. Setting University hospital. Patient(s) Three hundred and forty healthy women aged 18–35 years randomized to treatment, of whom 332 completed the data collection at follow-up evaluation. Intervention(s) A combined OC (150 μg levonorgestrel and 30 μg ethinylestradiol) or placebo for 3 ...

Context: There is a lack of knowledge about how oral contraceptives may affect sexual function. Objective: To determine whether there is a causal effect of oral contraceptives on sexuality. We hypothesized that a widely used pill impairs sexuality. Design: A double-blind, randomized, placebo-controlled trial. Enrollment began in February 2012 and was completed in August 2015. Setting: Karolinska University Hospital, Stockholm, Sweden. Participants: A total of 340 healthy women, aged 18–35 years,...

Estrogen hormones have a large impact on both normal development and tumorigenesis of the breast.Breast tissue samples from 49 women undergoing surgery were included. The estrogen receptors (ERα and ERβ), ERα36 and G-coupled estrogen receptor-1 (GPER) were determined in benign and malignant breast tissue.The ERα36 and ERα mRNA levels were highest in malignant tumors. Stromal ERβ immunostaining in benign tumors was higher than in the paired normal tissue. GPER expression was lowest in benign tumo...

This study sought to investigate the prevalence of osteoporosis and the role of sex hormone levels in the determination of bone mineral density (BMD) and osteoporosis in a Vietnamese population of women and men. The cross-sectional study involved 269 women and 222 men aged 13–83 years, who were randomly selected from urban and rural areas in northern Vietnam. Serum concentrations of estradiol and testosterone were analyzed, and BMD was measured by dual X-ray absorptiometry. We found that the pre...

AbstractUnintended pregnancy is an important public health problem worldwide. Unwanted pregnancies may end in induced abortion (legal or illegal, safe or unsafe) or in childbirth. In many parts of the world both can be life threatening. Even where both are safe, abortion is distressing for all concerned while unwanted births often lead to poor health and social outcomes for both the mother and her child.

Both estrogen and testosterone insufficiency has been associated with reduced psychological well-being including fatigue. However, hormonal replacement studies on fatigue are rare. Therefore, we wanted to study the effect of testosterone and estrogen replacement therapy on cognitive fatigue and the relation between sex hormone levels and cognitive fatigue in oophorectomized women. Fifty women with surgically induced menopause (mean age: 54.0 ± 2.9 years) were randomly assigned to treatment with ...
